Project overview The RePublic_ZEB project is focused on the energy and CO2 emissions associated with existing public buildings and their refurbishment towards nZEB. The core objective of the project is to:

• Define costs-benefit optimized “packages of measures” based on efficient and quality-guaranteed technologies for the refurbishment of the public building stock towards nZEB that are standardized and adopted by builders and building owners.

From this stems three basic objectives: (i) State-of-the-art assessment of the public building stock through a country-specific

evaluation of the energy consumption and CO2 emissions;

(ii) Define reference buildings; and;

(iii) Develop a common framework and a harmonized methodology for the definition of a nZEB concept for public buildings.

1. EXECUTIVE SUMMARY This document is developed within Task 4.1 “Definition of a methodology and the relevant tools for determining the energy use (fossil and renewable) and the cost optimal levels of the reference buildings” of RePublic_ZEB project.

According to RePublic_ZEB Description of the Action “Concerning the cost optimal evaluation, it is country specific, thus CTI (and POLITO) will define a second common methodology and will develop a relevant tool (an Excel file) to calculate the optimal levels of minimum energy performance requirements (MEPR) towards nZEB for each participating country. The comparative methodology framework will be based on the cost optimization procedure described below. The calculation of cost optimal MEPR for each reference building will be achieved using a cost optimization proposal based on a sequential search optimization technique. The method allows discrete rather than continuous building energy efficiency options (e.g. different levels of insulation). The different options are applied one at a time in order to find at each step a new partial optimal building. A reference set of energy efficient options are assumed as start point of the optimization procedure. The net present value (NPV) of each set of energy efficient options is defined by comparison with the reference set.”

The present document is finalised to explain the common methodology for the calculation of the optimal levels of minimum energy performance requirements towards nZEB, and to collect the country assumptions for the global cost evaluation.

2. INTRODUCTION According to WP4 proposals, partners are going to define for each reference building the most suitable energy efficiency measures in order to achieve the nZEB goal. As commonly defined in D4.1, for the purposes of RePublic_ZEB project, a building is considered as nearly Zero Energy when the following requirements are met:

a) the EP is lower than the cost-optimal level (a nZEB is more energy efficient than the cost-optimal building);

b) the differential Global Cost (∆GC) is negative (nZEB is cost effective)1;

c) the national minimum energy performance requirements for nZEBs are fulfilled.

Here is given an explanation of the above requirements:

• As specified in prEN ISO/DIS 52000-1:2015, the Energy Performance (EP) is expressed as the building global primary energy demand divided by the conditioned area. The global primary energy refers to all the EPBD energy services (heating, cooling, DHW, ventilation, lighting) and is calculated according to the Standard. EP can either include only non-renewable energy (EPnren), or include both non-renewable energy and renewable energy (EPtot):

EPtot = EPnren + EPren

• The Renewable Energy Ratio (RER) is the ratio of the renewable primary energy to the total primary energy:

RER = EPren /EPtot

• The Energy Performance is fully described by a couple of indicators: EPtot and EPnren , or alternatively

EPtot and RER

• The Global Cost (GC) is the net present value of all costs (referred to the starting year), determined according to EN 15459. The Global Cost is linked to the calculation period (usually 30 years) and includes investment costs for refurbishment; replacement costs; running annual costs. The differential Global Cost (∆GC) considers the extra-costs referred to a baseline building.

In principle, a large number of packages and variants could be considered: each dot in Fig. 1 represents a package of energy efficient measures through the differential Global Cost (∆GC) referred to the existing building versus the Energy Performance (EP) 2.

1 It could be discussed whether a very high-energy efficiency, but slightly non cost-effective solution could be acceptable. 2 The outlook of Figure 1 will be different depending on whether the EP on the abscissa axis expresses a total primary energy (EPtot) or a non-renewable primary energy (EPnren).

Figure 2.1. Differential GC vs. EP

From the analysis of Fig. 1 it is possible to set out the following considerations: • The existing building corresponds to the highest EP and to ∆GC equal to 0 (zero

investment costs and zero periodic extra-costs, as the existing building itself is assumed as the baseline).

• After an energy refurbishment the energy costs are always negative, while the differential Global Cost is negative whenever the refurbishment proves to be cost effective.

• All the data points (packages/variants) lay on an area, which is delimited below by a specific cost curve, which represents a Pareto frontier: starting from a point staying on this curve it is impossible to find a solution with lower Global Cost without modifying the energy efficiency.

• The cost-optimal level means the energy performance level that leads to the lowest Global Cost during the estimated economic lifecycle. Due to uncertainties and calculation simplifications it is more correct to define a cost optimal range rather than a precise cost-optimal point.

• The dashed line represents the national legal EP requirement in 2015. According to the EPBD recast the member States should take the necessary steps to significantly reduce the gap between this EP requirement and the cost-optimal level of minimum energy performance.

• The nZEB range should have a primary energy consumption lower than the cost optimal solution, and the Global Cost in between the cost optimal case and the actual reference building.

Thus, the cost optimal solution for each reference building as well as the Global Cost of the current building have to be determined.


RePublic_ZEB © 2015 of 173 21/12/2015

According to the Commission Delegated Regulation (EU) No. 244/2012 [1] supplementing the Directive 2010/31/EU [2] and to the Guidelines accompanying the Regulation [3], the MSs have identified the optimal cost levels for the minimum EP requirements for new or existing buildings, or parts of it. They also have compared the results of these calculations with the minimum EP requirements in force. Concerning the cost optimal evaluation, it is country specific, thus POLITO and CTI will define a second common methodology and will develop a relevant tool (an Excel file) to calculate the optimal levels of minimum energy performance requirements (MEPR) towards nZEB for each participating country. The tool will be based on the Italian cost optimal methodology framework, but it will be modified in such a way as to consider the partners’ assumptions. D4.2 aims at describing the cost optimal evaluation tool and at collecting the country assumptions needed for the cost optimal methodology application (i.e. energy costs, investment costs, operating and maintenance costs, discount rate and calculation period) and the further nZEB investigation. The final goal is to define a common but country specific tool, in order to let the comparison among partners more effective.

3. THE GLOBAL COST CALCULATION The Commission Delegated Regulation No. 244/2012 requires the evaluation of the cost-optimal level both at a macroeconomic and at a financial level. Concerning the macroeconomic level, the global cost is defined by considering the costs corresponding to the CO2 emissions too, as the monetary value of the environmental damages caused by the emissions related to the building energy consumption. Concerning the financial level calculation, the methodology is based on the overall costs, considering the initial investment, the sum of the annual costs for each year (energy, maintenance, operation and any additional costs), the extraordinary replacement of systems and components, the final value, and the costs of disposal, as appropriate. All costs are actualized to the starting year. For the RePublic_ZEB purposes, the financial perspective calculation will be applied without considering subsidies, as the Guidelines state “It has to be noted that, for the financial perspective calculation, the inclusion of available support schemes (along with taxes and all available subsidies) would usually be required to reflect the real financial situation. However, given that such schemes often change quickly it is also possible for a Member State to calculate without subsidies for a private investor point of view”. The financing framework methodology is based on the net present value (global costs) calculation, carried out according to Standard EN 15459:2007 [4], which provides a method for considering the economic aspects related to the application of heating systems and other technical systems that affect the energy consumption of the building. According to this Standard, the calculation of the global cost Cg(t) referred to the starting year t0 may be performed by a component or system approach, by considering the initial investment CI, and for every component or system j, the annual costs Ca and the discount factor Rdisc(i) for every year i (referred to the starting year), the final value ValF. The global cost is directly linked to the duration of the calculation period t, as shown in Eq. (1).

(1) The energy renovation costs have been evaluated by a full cost approach, including design, purchase of building elements, connection to suppliers, installation and commissioning process. These costs are those presented to the customer taking into account also the cost of ancillary works, e.g. scaffolding of a new chimney, professional fees and taxes. However, since the focus of the exercise is the comparison of measures/packages/variants (and not the assessment of total costs for the investor and building user), the following cost items may be omitted from the calculation:


RePublic_ZEB © 2015 of 173 21/12/2015

• Costs related to building elements which do not have an influence on the energy performance of the building, for example: cost of floor covering, cost of wall painting, etc. (if the energy performance calculation does not reveal any differences in this respect);

• Costs that are the same for all measures/packages assessed for a certain reference building (even if the related building elements have or could have an influence on the energy performance of the building). Since these cost items do not make a difference in the comparison of the measures/packages, it is not required to take them into account. Examples could be: cost of scaffolding, demolition cost, etc. – once again under the precondition that no differences in these cost items can be expected for the measures/packages/variants assessed.

The replacement costs are those needed to substitute components or systems at the end of their lifespan. Annex A of EN 15459 has been used as a reference for the definition of lifespan, which is the economic lifetime expectancy for a component or a system. No price development rate in real terms has been assumed for replacement costs. The running costs include maintenance cost, operational cost and energy cost for the time step considered. The residual value (also called final value) of a component is determined by straight-line depreciation of the initial investment until the end of the calculation period and referred to beginning of the calculation period. Replacement costs and residual values are necessary to correctly compare measures with different lifespan. The Guidelines accompanying the Regulation summarizes the cost categories to be applied in the following Figure 3.1.

Figure 3.1. Cost categorization according to the framework methodology

The discount factor Rdisc(i), for every year i, is a multiplicative number used to convert a cash flow occurring at a given point in time to its equivalent value at the starting point. The discount factor is derived from the discount rate r and is calculated as in Eq. (2) where i is the number of years from the starting period.

(2) According to the Guidelines accompanying the Regulation, a higher discount rate – typically higher than 4% excluding inflation – would reflect a purely commercial, short-term approach to the valuation of investments. A lower rate – typically ranging from 2% to 4% excluding inflation – would more closely reflect the benefits that energy efficiency investments bring to building occupants over the entire investment’s lifetime. The discount rate is set at country level. The calculation period should be 30 years for public buildings, according to the Regulation.

4. THE COMMON TOOL An energy cost optimization procedure based on a sequential search-optimization technique has been developed and it will be applied to each reference building, to calculate of the cost-optimal energy performance. The procedure refers to the model developed in US [5]. The method


RePublic_ZEB © 2015 of 173 21/12/2015

considers, for each energy efficiency measure, a discrete number of options (e.g. different levels of thermal insulation), described by relevant parameters (e.g. thermal transmittance). Different packages of energy efficiency measures are applied and compared: each package is a set of energy efficiency options, one for each measure. A reference package of energy efficiency options is assumed as the starting point of the optimization calculation; the cost associated with each package of energy efficiency options is defined by comparison with the reference set. Subsequently, the procedure allows to identify a sequence of configurations (packages of energy efficiency measures) that constitute the “partial optimums”. To switch from a partial optimum to the next one, all the parameters that characterize the levels of each energy efficiency measure are modified one at a time. Among all the tested configurations, the next partial optimum is that which allows the highest reduction in terms of global cost. The flow-chart of the calculation path and of the optimization procedure are shown in Figure 4.1 and Figure 4.2, respectively.

Figure 4.1. Flow chart of the calculation path.


RePublic_ZEB © 2015 of 173 21/12/2015

Figure 4.2. Flow chart of the cost optimization procedure.

The energy efficiency measures (EEMs) applied to each reference building have been defined by the partners for each reference building, and are reported in Appendix. One or more appropriate parameters are associated to each measure; e.g. the thermal transmittance for the thermal insulation of the building envelope, the heat generator efficiency for the technical systems replacement, the collectors area for the thermal solar system installation, the peak power for the photovoltaic system installation. For each measure, up to five energy efficiency options or levels (EEOs) are defined. The energy performance is calculated as specified in D4.1, and the global cost analysis is performed according to EN 15459, as specified in Section 3. Figure 4.3 shows an example of a set of partial optimum points related to different applications of the optimization procedure to the same case study, starting from different sets of EEOs.

Figure 4.3. Partial optimum points and cost optimal range.

The procedure has proved to be robust, as regardless the chosen starting point, it leads to the same optimum level, which corresponds to the minimum global cost. In Figure 4.3 the optimal range of the ratio between global cost and energy performance is also shown, in qualitative terms, according to the Guidelines of the European Commission.

Figure 4.4 shows the initial investment cost, the energy cost and the operational cost, for each partial optimum point of an optimization path of Figure 4.3. The optimization tool also gives the energy need for heating, cooling and domestic hot water, as well as the energy use for the considered end uses, the energy performance and the renewable energy ratio.

5. COUNTRY ASSUMPTIONS Section 0 reports on the country assumptions for the costs evaluation, according to Figure 3.1. The actualized global cost has to be calculated both for the reference buildings at current state and after the refurbishment, in such a way as to define the zero level of Figure 2.1. As regards the current state of the reference building, only the running costs and the energy costs will be considered.

5.1 BULGARIA

5.1.1 Initial investment costs The initial investment cost associated to each EEO is got either from extensive market surveys or from official databases. A summary of investment costs is presented in Appendix. None of the available national support schemes (e.g. tax credit, white certificates, etc.) is considered so as to make a conservative evaluation. Furthermore, it has to be noted that such schemes often change quickly.

5.1.2 Running costs: operational and maintenance There are no reliable data about the running cost in Bulgaria. They are subject of contracting between the users and utilities. A rough estimate is 1,68 Euro per square meter, but it seems too low. As regards the post-refurbishment scenario, the maintenance costs are considered as a percentage of the initial investment cost, for each year of the calculation period. According to the Guidelines, the guidance given in standard EN 15459 (for energy systems in buildings) and other official data sources are considered.

5.1.3 Energy costs ELECTRICITY The electricity tariffs in Bulgaria are regulated by the Energy and Water Regulatory Commission in line with the requirements of the Energy Act. The Commission regulates the prices:

• at which the producers sell electric energy to the public supplier; • at which the public supplier sells electric energy to the operators of the power transmission

and distribution networks for covering the technological costs for transmission; • at which the public supplier sells to the end suppliers; • at which the end suppliers sell electric energy to households and non-household end clients

for sites, joined to the low voltage electric distribution network; • for access and transmission through the electric distribution networks;


RePublic_ZEB © 2015 of 173 21/12/2015

• the price or the price component through which all end users, joined to the power network, participate in the compensation of the non-restorable expenses and the expenses ensuing from the required obligations to the public (incl. reliability of supply, protection of environment, energy efficiency).

The price tariffs are determined once per year, but the Commission has the right to adjust them during the price period under certain conditions. The regulated electricity prices are applied by the 4 main suppliers, servicing the different geographical regions in the country (CEZ – operates in Western Bulgaria, EVN – operates in Central and Southern Bulgaria, Energo-Pro – operates in Eastern Bulgaria, and Golden Sands – services the vacation complex Golden Sands).

The end price of electricity for households at the regulated market is composed of two main components: price for power supply and price for power distribution. The total amount of the two components is levied with 20% VAT. The supply price is defined according to two tariffs – day and night. The clients may choose between one and two scale measuring. The electricity for households is not taxed with excise. The price for distribution is formed by the prices of: access to the distribution network, access to the transmission network, power transmission through the distribution and transmission networks, green energy, high efficient CHP and unrecoverable costs. The end tariffs for households of the four suppliers are presented in the table below.

NATURAL GAS The price of natural gas is defined according to the provisions of the Energy Act and in line with the Ordinance No.2 from 19.03.2013 on the regulation of natural gas prices. The Energy and Water Regulatory Commission approves and regulates the prices for natural gas distribution and supply to end users requested by the licensed suppliers. There are about 30 natural gas distribution companies operating on the territories of the 5 supplied with natural gas regions.


RePublic_ZEB © 2015 of 173 21/12/2015

The price of natural gas for the end users includes three components:

• the price at which the public supplier sells natural gas to the end suppliers. (It includes the price of the resource and the price for its transportation through the distribution network of the public supplier);

• the price of transmission/distribution through the network of the licensed distribution companies;

• the price of supply with natural gas, which covers the expenses of the licensed company. Natural gas tariffs are different for each supplier. Also there are (slightly) different consumption levels and users (business, domestic, administrative). Here we present the tariffs applied to the consumers in Sofia and Varna, the regions that are concerned by the current project study. The territory of Sofia is operated by Overgas Networks, which sells natural gas at the prices, as shown below:

5.3.2 Running costs: operational and maintenance As regards the maintenance costs of the actual reference buildings, these values result from investigations on the current utilities. Table 5.14 and Table 5.15 provide indicative maintenance yearly costs for each reference building respectively; in the same table for each building component and technical system, the replacement cost is reported. The values reported in the Tables are referred to the state of art, i.e. yearly costs of maintenance, cost and year of replacement (if relevant) for the case the reference building is not refurbished. As regards the post-refurbishment scenario, the maintenance costs are considered as a percentage of the initial investment cost, for each year of the calculation period. According to the Guidelines, the guidance given in standard MKS EN 15459 (for energy systems in buildings) and other official data sources are considered.

5.4.3 Energy costs ELECTRICITY The costs of electricity are derived from the Public Power Corporation S.A. (PPC), considering the current market tariffs. There are different electricity market prices for residential and non-residential users. Four basic tariffs are for residential users and three for non-residential users.


RePublic_ZEB © 2015 of 173 21/12/2015

Electricity market tariffs are composed of regulated and competitive charges. Regulated charges include the charges of the transport and distribution network and also the ones of the public utility services. The consumption period is four months (120 days), the power charge is per kVA and agreed power and the energy charge is per kWh. The most common tariffs for households are the “non-Off-Peak Tariff G1”. A uniform charging price is calculated for the 24-hour consumption, the amount of which is differentiated according to the total amount of the 4-month consumption period. The Residential Night Tariff “Off-Peak Tariff G1Ν” is a tariff that includes two charging prices, that is, the consumption within the 24-hour period is calculated using two different prices. So, the consumption within the peak period is charged with the regular price (residential non-Off-Peak Tariff - G1), while the consumption within the off-peak period is charged with a reduced price. The reduced tariff for multi children families “GT” is established with the decision of the Committee for Prices and Revenues (no 2153/3.4.96) which defines that the beneficiaries should be multi children families with 4 dependent children or more. Since 2010, the Social Residential Tariff (SRT - ΚΟΤ) is provided for the protection of the vulnerable social groups of consumers and particularly for persons with low income, families with 3 dependent children, long-term unemployed, disabled people as well as people on life support. The electricity prices for all the above mentioned tariffs are presented in the following tables (Table 5.24 - Table 5.30).

The non-residential users in the rest regions of Greece are supplied by the Public Gas Corporation (DEPA S.A.). The market tariffs differ each month due to the different monthly mix of natural gas (from three different countries). Table 5.31 present the natural gas market tariffs of October 2015.

5.5.3 Energy costs ELECTRICITY There is a high variety of electricity tariffs that can be chosen either for residential or for small companies, and institutions or for big industrial companies. The main groups of tariffs are based on the voltage level: low voltage is 230 V or 400 V, middle voltage is usually 10 kV (can be 20 kV or 35 kV, too), and high voltage is above 35 kV. There are big differences is the conditions and prices, but the buildings. The public buildings in Hungary use the low-voltage supply, and only the biggest public buildings use the middle-voltage supply. The reference buildings presented in this project can use only the low-voltage supply.

All the low-voltage tariffs contain five kind of costs: the fixed charge must be paid for every month, the energy prices and the network prices depend on the consumption, the VAT is added to all the three before, and some additional special costs depend on the consumption, but VAT free.

All these costs are derived from the national authority for every tariffs, but can be different based on the location in Hungary (there are four regions). The costs are different for the residential and non-residential customers. Additionally everyone has the possibility to contract with a supplier and make an arrangement on the energy prices based on the “free market”.

Energy prices

The low-voltage tariffs are defined according to the sort of the usage. The available tariffs are named with letters and numbers: A1, reduced A1, A2, A3, B, B-Geo, H.

The basic tariff is called A1, most of the residential customers use this one, but non-residential customers can choose it, too. There is no difference between the peak hours and the off-peak hours. For the residential customers the consumption till 1320 kWh/year is calculated by the reduced A1 tariff, the A1 is used only above this amount.


RePublic_ZEB © 2015 of 173 21/12/2015

With an electricity meter capable of detached measurement in peak hours and off-peak hours the tariff A2 can be chosen, too. The peak hour costs in A2 are 20-25% higher than A1, but the off-peak hours costs are about 25% lower.

The tariff A3 is similar to A2, but it can be chosen only by public institutions.

The tariff B is available only as additional supply, as the electricity meter can be switched off by the supply company. The operation time is at least 7 hours a day in summer time and 8 hours a day in winter time, but this time is mostly in off-peak hours. This tariff is used for electricity based DHW or heating systems, when the buffer is big enough.

A special type of tariff B is tariff B-Geo. The costs are a little higher than in tariff B, but the operation time is at least 20 hours a day. Only heat pumps with COP=3 or higher can be operated with this tariff.

Only for heat pumps with COP=3 or higher is available the tariff H, too. The costs are lower than tariff B-Geo, and the operation time is 24 hours a day, but can be used only from 15th October to 15th April. The consumption in summer time is calculated with tariff A1.

The network prices are calculated according to the consumption, too. The rate is based on if the used tariff is for general usage, or additional supply. The prices for residential, non-residential customers and public institutions are different. The energy tax is usually also calculated in the network prices, it is paid by all non-residential customers and it is subject to VAT.

The fix charges are paid every month, it does not depend on the consumption. As the network prices, it is different for residential, non-residential customers and public institutions. Additional power charge is not calculated on low-voltage supply (only above 34,5 kW, but that is usually cheaper on middle-voltage supply).

The additional costs are paid by non-residential customers for three purposes: one is for the cost of reducing a coal based power plant operation, one is for a reduced tariff (called tariff C, not presented here) which is available only for some people working in the power industry, and one is for grant of the cogeneration power plants.

The VAT is 27%, only the additional costs are not subject to VAT.

Installing PV panels on a building under 50 kWp power is worth only if the whole consumption will be used in the building. In that case the energy costs will be calculated based on the difference of the generated and used energy in a year. If the generation is higher than the usage, only some energy prices will be payed, but income-tax have to be payed from it.

Table 5.35 presents all the net costs for low-voltage electrical energy supply in the Budapest region.

For the purposes of the present work, the following assumptions are made:

• Tariff A1 is used for all the reference buildings in general. (In fact the office building and the student hostel is big enough to contract on the “free market” and reach 10% reduction on the total prices.)

• Tariff B is used for electricity based DHW production. • Tariff H is used for all the heat pumps.

NATURAL GAS The tariffs of the natural gas are simpler than the tariffs of the electricity. The prices are different in the four region of Hungary, but derived from the national authority. Most of the residential users have a gas meter with a capacity under 20 m3/h (class A1). For them a reduced price (category I.) is available under a consumption of 41040 MJ/year (~1200 m3/year), above this amount the normal prices (category II.) are used. They have a fixed charge calculated Ft/year. Some residential users have a gas meter with a capacity above 20 m3/h (class B1). Their prices are only in category II, and the fixed charges are calculated Ft/(m3/h)/year. Non-residential users with a gas meter with a capacity under 20 m3/h (class A2) can use the reduced category I. till 41040 MJ/year, above that the category II. shows the prices. The fixed charges are calculated Ft/year. Non-residential users with a gas meter with a capacity of 20 m3/h (class B2) can use only the prices of category II, and the fixed charges are calculated Ft/(m3/h)/year. Above 20 m3/h all the non-residential users have to contract on the “free market”. All the non-residential users have to pay extra charges for the safety storages and energy tax, both are subject to VAT. The network prices are included in the energy prices. The VAT is 27%, all the costs are subject to VAT. Table 5.36 presents all the net costs for natural gas supply in the Budapest region.

For the purposes of the present work, the following assumption is made:

• Tariff A2 is used for all the reference buildings in general. DISTRICT HEATING The prices of the district heating is different at every supplier company, but derived from the national authority. The total price includes fixed charge, energy price and VAT. All the prices are different for residential and non-residential users. The fixed charge depends on if the heating centre is owned and operated by the supplier company or the building owner. If it is operated by the supplier company, the user can choose if the fixed charge should be calculated based on the heated net building volume or the needed power (the second cannot be chosen for residential users). If the heating centre is operated by the building owner, the fixed charge can be calculated only based on the needed power. The energy prices depends only if the user is residential or non-residential. The non-residential users can choose to contract on the “free market”. As there is only one supplier at one location, the negotiation is usually about to use district heating or natural gas. With this negotiations the non-residential users can achieve even half of the fixed charge shown in table below. Usually there is only little difference in the energy prices. The VAT is 5% for all the prices above. Table 5.37 presents all the net costs for district heating supply in the Budapest region.

5.6.3 Energy costs The information provided in Annex 2 of the Regulation is taken from the energy trend scenarios developed with the PRIMES model, i.e. a modelling system that simulates a market equilibrium solution for energy supply and demand in the EU27 and its Member States. The baseline price assumptions for the EU27 are the result of world energy modelling (using the PROMETHEUS stochastic world energy model) that derives price trajectories for oil, gas and coal under a conventional wisdom view of the development of the world energy system. According to [6], the trends of the energy prices may be extrapolated beyond 2030 until more long-term projections become available. In order to consider the whole estimated economic lifetime of the reference buildings, the extrapolation is done up to 2050, by considering the percentages of Figure 5.1. For biomass and district heating, the natural gas trend is used.


RePublic_ZEB © 2015 of 173 21/12/2015

Figure 5.1. Energy price trends, for electricity and natural gas.

ELECTRICITY The costs of the energy carriers are derived from the National Authority for Electricity and Natural Gas (AEEG), considering the captive market tariffs. The estimated energy carriers price development trends are those provided by the European Commission on a biannually updated basis (PRIMES model), according to Annex 2 of the Commission Delegated Regulation No. 244/2012. These trends have been extrapolated beyond 2030, which is the last year taken into account in the available projections. Electricity captive market tariffs are composed of a fixed fee, a per-unit charge and an amount related to the maximum power. The per-unit charge has a time of use pricing consisting of two periods (peak hour and off-peak hours) depending both on the day of the week and on the time of day. Furthermore the pricing is related to the maximum allowed power. The most common tariffs for households is the so-called “D2”, dedicated to primary residences and allowing a maximum power of 3 kW. This tariff has increasing block rates, i.e. the per-unit charges increase when the amount used increases. It means that the cost of electricity for HVAC services is affected by the amount of electricity used for other services (lighting, washing, cooking, etc.). The tariff “D3” is dedicated to primary residences and allowing a maximum power higher than 3 kW. Finally, the tariff “BTA” allows a maximum power higher than 16.5 kW and it is available for apartment blocks (in case of centralized energy consumptions), and for non-household users. Concerning taxes on electricity, there are excise (depending on the amount of electricity used, maximum allowed power and kind of dwelling) and VAT (10% for tariffs D2 and D3, 23% for tariff BTA). Table 5.45, Table 5.46 and Table 5.47 show the electricity price for D2, D3 and BTA tariffs respectively. A single time slot is considered. Values are referred to the cost optimal national application [8] (2013).

For the purposes of the present work, the following assumptions are made:

• Tariff D2 is used for social housing, when autonomous electricity consumption occurs (i.e. actual electrical DHW heater);

• Tariff D3 is used for social housing, when high autonomous electricity consumption occurs (i.e. heat pump for DHW);

• Tariff BTA is used for the centralized electrical consumption of social housing, and for schools and office;

• 2700 kWh/a are considered per dwelling, for services other than space heating and cooling and DHW;

NATURAL GAS Natural gas captive market tariffs are differentiated both by region and by individual and centralized uses. There are three taxes on natural gas consumption: excise (depending on location and amount of natural gas used), VAT (10% up to 480 Sm3, 23% beyond 480 Sm3) and local taxes (if appropriate). Table 5.48 shows the natural gas prices for residential and non-residential users respectively, for the North and North-West of Italy.

5.9.1 Initial investment costs The initial investment cost associated to each EEO is got either from extensive market surveys or from official databases. A summary of investment costs is presented in Appendix, for each reference building and used calculation tool for EPC. According with Deliverable D4.1, three tools are going to be used: common, Slovenian and IDA ICE. Not all scenarios are going to be calculated with each tool, the tables in Appendix present scenarios for reference buildings and tools respectively, on which the initial investment costs relate to. None of the available national support schemes (e.g. tax credit, white certificates, etc.) is considered to make a conservative evaluation. Furthermore, it has to be noted that such schemes often change quickly.

5.9.2 Running costs: operational and maintenance As regards the maintenance costs of the actual reference buildings, these values result from investigations on the current utilities. Table 5.67 provides indicative maintenance and operational yearly costs for each reference building respectively; in the same table for each building component and technical system, the replacement cost and the referred year in between the calculation period is reported, if relevant. The maintenance and operational costs are considered as a percentage of the initial investment cost, for each year of the calculation period. According to the Guidelines, the guidance given in standard EN 15459 (for energy systems in buildings) and other official data sources are considered.

ELECTRICITY The costs of the energy carriers are derived from the Statistical Office of the Republic of Slovenia (SURS), considering the captive market tariffs. The estimated energy carriers price development trends are those provided by the European Commission on a biannually updated basis (PRIMES model), according to Annex 2 of the Commission Delegated Regulation No. 244/2012. These trends have been extrapolated beyond 2030. Looking at the period between 1992 and 2015, the increase in electricity prices in industry has been a substantial. On average, the industry electricity prices increased by more than 4% a year between 2010 and 2015 (excluding VAT and recoverable taxes). Regulated network tariffs are set ex ante following a consultation process by the Energy Agency. Network charges are set for transmission and distribution levels separately, based on the utilization and customer categories. Network tariffs for each customer category are uniform across the country. Network tariff categories are: voltage level, connection to substations, utilization, seasonality, night/day use; household and public lighting. Regulated full service tariffs for end customers do not exist.


RePublic_ZEB © 2015 of 173 21/12/2015

The network tariff methodologies are incentive-based price cap, and include performance-based components. Additional quality-based incentives are planned (from 2011). The household price of electricity in Slovenia is not significantly lower than the average price in the EU-27. Generators are not charged for accessing the network; customers pay 100% of network charges. There have been no cases of refusal of access except as a result of cross border congestion. Mechanisms for the calculation of total transfer capacity are proposed by the TSO. According to EU Regulation 1228/2003, these mechanisms should be subject to approval of the regulatory authority; in practice this has not yet occurred. Concerning taxes on electricity, there are excise (depending on the amount of electricity used (IA - IF), maximum allowed power and kind of dwelling) and VAT. For the purpose of this work, a standard tariff (national average) has been chosen for all reference buildings. Table 5.69 shows the electricity prices for tariffs classes respectively, where the prices present the status for 2014.

NATURAL GAS The Slovenian market for natural gas has been fully opened since July 2007. All customers, including households, have the option to switch gas supplier, but the distribution of natural gas will still be provided by the current system operator. Slovenia depends almost entirely on imported gas; in 2007, 50% came from Russia, 30% Algeria and 19% from Austria. Looking at the period between 1992 and 2015, the increase in electricity prices in industry has been a substantial. On average, the industry electricity prices increased by more than 3 % a year between 2010 and 2015 on average (excluding VAT and recoverable taxes).

Because the market is fully unbundled, there are no end-user regulated tariffs. There is regulated Third Party Access; a price cap methodology is used for the network tariffs. The Agency may impose performance-based components. The Agency licenses all activities on the gas market separately, as in electricity. Concerning taxes on natural gas, there are excise (depending on the amount of electricity used (IA - IF), maximum allowed power and kind of dwelling) and VAT. For the purpose of this work, a standard tariff (national average) has been chosen for all reference buildings. Table 5.70 shows the natural gas prices for tariffs classes respectively, where the prices present the status for 2014. BIOMASS Wood is the most important renewable energy source in Slovenia. In 2009 more than 330,000 households used wood for heating and this number is still growing. In Slovenia firewood is traditionally used for heating, however in recent year’s use of wood chips and pellets increased. The yearly wood biomass consumption depends on the length of heating season and the low winter temperatures. Beside more frequent use of wood in households, number of district heating systems also increased. Nearly 80% of wood used for heating originates from forest and the remaining 20% form unwooded areas. Wood biomass is mainly used (95%) for the production of heat, especially in households. The main problems are the conventional systems with obsolete technologies with relatively low efficiency and high emissions. Modern technologies are applied progressively. Prices of wood fuels are rising in last year’s, however it is difficult to follow the trends, since an official system for monitoring wood fuels prices don’t exists in Slovenia. The SURS is collecting only data about the average prices of wood fuel. According to this data the prices of wood fuel (deciduous trees) increased for 20% between 2010 and 2011 and decreased for 4% between 2011 and 2012. Average price of wood fuel (deciduous trees) in 2012 according to SORS was 38,07 €/m3. SFI controls/monitors wood fuel prices in selected European countries in the frame of IEE project BiomassTradeCentre2. During the project period data on wood fuel prices are collected in partners countries (Austria, Croatia, Germany, Greece, Ireland, Italy, Romania, Slovenia and Spain) at the beginning and at the end of each heating season. Prices for the following wood fuel categories are collected for:

- firewood with the length of 25, 33, 50 and 100 cm, and moisture content of 20% or 50%, - wood chips category’s P16, P31.5, P45, P63, P100, and water content of 20%, 30%, 40% or

55%, - wood pellets: price per ton, the price for a bag (15 kg or 20 kg), with a water content of 10%, - wood briquettes: price per ton, the price for a bag (10 or 15 kg), with a water content of 10%.


RePublic_ZEB © 2015 of 173 21/12/2015

Wood Chips According to SFI monitoring of wood fuel prices the average price of wood chips (P31,5; M = 30%) in 1st half of year 2013 in Slovenia was 86,6 € per ton dry matter, collected prices were in the interval between 84 and 93 € per ton dry matter (including VAT). Wood Pellets SFI is also collecting prices of wood pellets. Average cost of wood pellets (6 mm, M = 10%) packed in 15 kg bags in March 2013 was 243 €/t including VAT (in the interval of 220 – 250 €/t). The current price (March 2013) for loose pellets is 222 €/t including VAT (in the interval of 216 – 228 €/t). Prices do not include the transport of pellets. Market tariffs are composed of a fixed fee, a per-unit charge and an amount related to the maximum power. There is no tariff classes for these energy carriers, so the price is fixed and used as such for the purpose of this work (Table 5.68, Figure 5.3). DISTRICT HEATING District heating in Slovenia is defined as a local optional public service, under certain legal requirements may also be implemented as a commercial activity of supply of end customers. The distribution of heat includes the supply of heat or cold from the distribution networks, and the operation of the system operator of the distribution network. Prior to the start of these services, or to distribute heat the providers have to obtain, from the Energy Agency, a license to produce heat for the district heating or cooling if the total installed thermal power of their production units is above 1 MW. In Slovenia in 2011, 87 of the 102 licence holders, active in 49 municipalities, were involved in heat supply. Of these companies, 58 were involved in both heat distribution for district heating and heat production for district heating of above 1 MW; 15 companies were only involved in the distribution, while the remaining 14 companies only produced heat. The data relating to the average retail prices for heat from the distribution networks have been taken from the current price-lists of selected business entities for the production and supply of heat for standard customer group D3b. The data relate to a selected number of Slovenian municipalities, whose amount of heat supplied to the households in 2011 accounted for 52.1% of the total supply. The standard customer group is a group with a connected load of 10 kW and an annual consumption of 34.9 MWh, using the heat for hot water and central heating. Figure 5.4 shows the average retail prices for heat from the distribution systems relating to selected Slovenian municipalities, calculated as a weighted average of the retail prices versus the number of heat customers. It also shows the average Slovenian retail heat price, calculated as a weighted average of the prices for a selected number of towns. The price for heat for household customers compared to 2010 increased on average by 8.3%; the highest price increases, namely 19.5%, affected customers in Jesenice.

5.10.3 Energy costs The energy cost evolution rate considered in the present study follows the values proposed in the report “Implementing the cost-optimal methodology in EU countries. Lessons learned from three case studies” [8]. They compare the implementation of the cost-optimal methodology in three countries and estimates the energy cost evolution rate in 2.8%, which is used in the present study. ELECTRICITY The electricity cost has been obtained from the Ministry of Industry, Energy and Tourism and the National Energy Agency (Instituto para la Diversificación y el Ahorro Energético, IDAE) from Spain. They develop a periodic report of the regulated energy prices, where defines the costs of the different tariffs. The electricity cost is formed by two terms: fix term and variable term. The fix term is the cost related with the power connexion and is a constant cost per power contracted. The variable term is related with the quantity of energy consumed. Table 5.75 describes the different tariffs from medium size consumers.

depends on the level of annual consumption (small, medium, large etc.) and, in addition, the size of the Climate Change Levy (CCL)5 is shown.

Figure 5.4. Cost of electricity in public/non-domestic sector Q2 2014/15.

Predicted future fuel prices are also made available for government policy evaluation purposes, and Figure 5.5 shows what this is likely to be for electricity in the public/non-domestic sector. Three scenarios are given: low, central and high.

5 The CCL was introduced by Government in 2001 to address the barrier of under-valuing energy efficiency

by taxing the supply of specified energy products such as electricity, gas and coal for use as fuels (for lighting, heating and power) by business consumers. High energy using sectors can elect to have a Climate Change Agreement (CCA) by agreeing to specific energy savings targets in return for paying a reduced rate of CCL on their energy bills.

5.11.4 Discount rate The UK Treasury produces guidance on how to undertake policy appraisal within the public sector. Much of this is contained in the so-called ‘Green Book’6 and this advocates a discount rate of 3.5% to discount future costs and benefits. This is used for time periods up to 30 years but for proposals longer than this the Treasury recommends using lower discount rates. Specifically, for time periods more than 30 years up to 75 years, a rate of 3% is recommended; and, for even longer periods, lower rates are given.

APPENDIX The present Section provides the EEMs list suitable for the refurbishment of the reference buildings for each country. For each measure, the energy performance level and the referred investment cost are considered. Moreover, the present Section provides the compatibility matrix for each EEMs list, which defines the combinations among EEMs in order to define the suitable packages of measures that the tool will consider during the optimization process.
